JET-CONDENSER.

Specification of Letters Patent. Application filed March 5, 1906. Serial No. 304,400.

Patented May 8, 1906.

To all whom it may concern:

. enters in the direction Be it known that I, LEO VON TRESCKOW, a citizen of Germany, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Jet-Condensers; and I do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present inventionrelates to improvements in jet-condensers; and it consists of an improved condenser in which the spray of water combines with the incoming vapor after the manner of an injector and in which no condensed water can secure access to the air-pump.

My invention will be understood by reference to the accompanying drawing, which shows a central vertical section through the condenser and in which the same parts are indicated by the same letters throughout the several views.

A represents the outer shell of the con- 1 denser, which terminates in a tapered bottom A, carried by thebase O, which is preferably in the form of an hour-glass, indented as at c, and which rests upon the Torricellian water-leg D. This water-leg should be more than thirty-two feet high to enable the water to be drawn off through the slots (1 without any inrush of air.

The vapor is brought to the condenser from the evaporator (not shown) through the pipe B, which is preferably ofless diameter than and opens immediately above the open end of the hollow cylinder'E. The injection-wateris sprayed through holes f in the bottom and sides of the pipe F, which pipe stretches across the shell of the condenser and passes through the walls of the hollow cylinder E, which cylinder has a funnlel-shaped bottom E terminating in a no'z z e e.

In the operation of the device the vapor of the arrow 1 and, passing down into the cylinder E, mingles with the spray of water coming through the pipe F in the direction of the arrow 2. The Water condensing the vapor causes a strong draft downward through the funnel E and the nozzle 6, and the water keeps on down into the water-legD and is carried off through the slots d in the direction of the arrow 4. Any air or vapor that maybe entrained is um-pump,

5 funnel-shaped bottom,

sucked up in the direction of through the annular passage outside of the funnel E and is carried by the pipe G to the airpump, (not shown,) following the direction of the arrow 3. Thus it will be seen that the condenser is converted into an effective injector which will not only condense the vapors of the boiling liquid effectively, but will do this rapidly and economically. urthermore, a highly eflicient separation of the water from the dry air or uncondensed vapor is secured, and this will throw less work upon the vacuum-pump than is the case with the condensers now most generally in use. Furthermore, by regulating the supply of injected water, as by any well-known form of valve or by regulating the speed of the vacuthe vacuum and temperature may be readily and conveniently regulated. Moreover, by using the injector principle herein described it is believed that the same results 1n condensation may be secured with a less quan tity of injected water than has hitherto been the case.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
